“(We) voted,” Naomi wrote at the top of the photo, adding an American flag and upside-down smiling face emojis.

Naomi, 30, is the daughter of the president's son Hunter Biden and his ex-wife Kathleen Buhle.

Naomi married her husband in November 2022 and exchanged vows in a private ceremony on the South Lawn of the White House. Naomi's wedding was the first at the White House in nearly a decade – and the first ever for a grandchild of a sitting president.

Both of her grandparents, the president and first lady Jill Biden, were in attendance. The Columbia University law graduate was walked down the aisle by both her father and mother, a source close to the family told PEOPLE at the time.

In a further nod to Naomi's bond with her mother, the bride wore lily of the valley, a tradition in her mother's family.

The couple announced their engagement in September 2021 and confirmed in early 2022 that they had chosen the White House as their venue. Their wedding was the first wedding on the White House grounds since 2013, when presidential photographer Pete Souza married Patti Lease in the Rose Garden.

In a previous interview with PBS News HourNaomi explained that her grandfather was the center of the close-knit Biden clan.

President Biden has long been open about the close bond he and each of his grandchildren share. Shortly before Biden's inauguration, Naomi, who also lives in Washington, DC, said TodayJenna Bush Hager said she was excited when she found out her “pop” would be living just a few miles away.

“We grew up together,” she said. “He made sure that we were all together for every single tradition, every holiday… I don't think there was a decision, no matter how big or small, that we didn't make as a family.”
